Following theoretical predictions of competing prolate and oblate potential-energy minima, we present experimental evidence for the coexistence of prolate and oblate nuclear shapes which are associated in a given nucleus with the same single-quasiproton orbital. Prolate I=2 and oblate I=1 bands observed in the I119 nucleus are proposed as built on an h11/2 proton with low K and high K, respectively.
